Your API does REST, but can it SLEEP?

SLEEP (Syncable Lightweight Event Emitting Persistence) is an emerging standard for distributed data sync using HTTP and JSON. A generalized version of CouchDB's much lauded built-in replication, SLEEP extends the REST architecture to define a way in which databases can offer syncable JSON APIs that foster open data innovation by allowing developers to replicate entire databases over the net.

---

SLEEP comes from the Apache CouchDB project which is now widely known for it's multi-master streaming HTTP + JSON replication. This is possible in part because of the CouchDB _changes feed, which is a particular API that lets you see if there have been any changes made to the database since last time you synchronized. CouchDB can efficiently implement the _changes feed because of one subtle difference between it and most other databases: it stores a history of all changes that happen to the database, including deletes.

If you synchronize data from a remote source and then the
